Just to add some reference to why it can take a long time to start a REPL (for example):
> As it turns out, Clojure start time is a complicated and multi-dimensional topic. Clojure projects are slow to start not only because of JVM — JVM itself starts in ~50 ms — but because of JVM specifics the classes are loaded slowly. Clojure projects are slow to start not only because of Clojure — Clojure itself starts in ~1 second — but because of Clojure specifics, the namespaces, especially not AOT-compiled one, are loaded slowly. And so on.
